Help needed syncing android phone

Hi folks, I'm a new user and I bought Ultimate Guitar Tab for Android phone.Great App. But I want to sync it to an account. Or save the tabs for later.I tried favouriting hundreds of tabs but when I went to look, many of the tabs were gone.It took me ages to get, too. Very frustrating.Can anyone tell me what I need to do to save all my fave tabs for offline use.

Also, Is it possible to manually download tabs to my pc and then transfer them to a UG Folder?
